FEBRUARY 23, 2010 – La Mirada, Calif. – Makita, a worldwide manufacturer of technologically advanced power tools that are more compact with less weight yet deliver industrial strength power and results, is proud to announce the release of its new 42 lb. AVT Demolition Hammer, model HM1317CB. This hard-hitting hammer is equipped with Anti-Vibration Technology, Makita’s exclusive counterbalance system that delivers more efficient hitting on the concrete with less vibration in the tool.

The new HM1317CB is the latest in Makita’s growing line of AVT-equipped concrete hammers.

“The new HM1317CB combines hard-hitting power and less vibration for more efficient hitting,” said Anthony Corwin, Makita product manager, commercial products. “The HM1317CB is engineered to be the most efficient breaker hammer in its class. And at 42 pounds, it’s easier to maneuver than a larger 60 or 70-pound model, but still delivers enough power to get the job done.”

More Work and Less Vibration, With Ease-of-Use Features

The HM1317CB has a powerful 14 AMP motor with soft start and constant speed control that provides 730-1,450 BPM and 34.9 joules of impact energy to handle the most demanding applications. The HM1317CB is equipped with AVT, Makita’s exclusive counterbalance system that reduces vibration for more efficient hitting power.

Makita engineered the HM1317CB with an electronic variable speed adjusting dial, enabling the user to set the speed to the application, and a “no hammering when idling” setting to help increase the tool’s life. In addition, HM1317CB has an enlarged carbon brush for increased tool life, and an automatic brush cut-out system for increased tool life. An L.E.D. service light indicates that they need to be replaced, or if there is trouble with the electric circuit.

Additional features include a rubberized ergonomic soft grip to provide more comfort and control, an easy-to-operate slide switch to increase productivity and allow for continuous use, and a side-handle that swivels 360 degrees for greater control. For added convenience, the HM1317CB has a 16.4 ft. cord and accepts commonly used 1-1/8” Hex steel.

Versatile Design for a Range of Applications

The HM1317CB with AVT is a hard-hitting demolition hammer that is ideal for concete contractors, demolition contractors, landscapers, municipal contractors, and general contractors seeking a best-in-class industrial quality 42 lb. demolition hammer. The HM1317CB is just another example of Makita’s commitment to innovative technology and best in class engineering.

About Makita’s Anti-Vibration Technology (AVT)

Makita has adapted the science of earthquake engineering into power tools with Makita’s Anti-Vibration Technology (AVT). AVT is an exclusive counterbalance design that provides the professional a power tool solution with up to three-times less vibration, less noise and more efficient power than the competition.

Seismic research has developed this damping science over years to absorb the shocks and protect buildings from devastation of earthquake vibrations. Makita’s exclusive AVT involves engineering where a mechanical damper, effectively a counterbalance weight, provides an equal and opposite force that puts a mass directly opposite the point at which the striker bolt delivers the impact. As vibration is eliminated power is efficiently increased, allowing more of the generated energy in the motor to be delivered to the tool bit.
